MasterSeal® NP 520 is a single component, siliconized acrylic latex sealant formulated to provide easy gunnability, tooling and a fast setting seal with minimal shrinkage. It provides enhanced adhesion and weatherability, making it an ideal solution for many interior and exterior sealing applications. Used as an acoustical sealant, MasterSeal NP 520 reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions. The sealant cures to a tough rubber to form a long-lasting acoustical seal. 

MasterSeal NP 520 also has been fire-rated and it meets Class A criteria set by NFPA 101 when tested according to ASTM E 84, “Standard Test Method for Surface Burning Characteristics of Building Materials.”
